| persistent foetal circulation syndrome | <syndrome> A syndrome of persistent pulmonary hypertension in the newborn infant, without demonstrable cardiac disease. It is characterised by cyanosis and acidosis, severe pulmonary vasoconstriction, hypertrophy of pulmonary arterial muscle, and elevated pulmonary vascular resistance, with resultant right-to-left shunting of blood through a patent ductus arteriosus and at times a patent foramen ovale. (12 Dec 1998) |
| circulation | <physiology> Movement in a regular or circuitous course, as the movement of the blood through the heart and blood vessels. Origin: L. Circulatio (18 Nov 1997) |
| circulation, foetal | The blood circulation in the foetus (the unborn baby). Before birth, the blood from the heart that is destined (in the pulmonary artery) for the lungs is shunted away from the lungs and returned to the greatest of arteries (the aorta). The shunt is through a short vessel called the ductus arteriosus. When this shunt is open, it is said to be a patent (pronounced pá tent) ductus arteriosus (PDA). The PDA usually closes at or shortly after birth and blood is permitted to course freely to the lungs. (12 Dec 1998) |
| circulation time | The time taken for the blood to pass through a given circuit of the vascular system, e.g., the pulmonary or systemic circulation, from one arm to another, from arm to tongue, or from arm to lung; it is measured by the injection into an arm vein of a substance, such as sodium dehydrocholate, ether, fluorescein, histamine, or a radium salt, which can be detected when it arrives at another point in the vascular system.

| collateral circulation | Compensatory circulation carried on through secondary channels after obstruction of the principal vessel supplying the part. (12 Dec 1998) |
| placental circulation | The circulation of blood through the placenta during intrauterine life, serving the needs of the foetus for aeration, absorption, and excretion; also, maternal circulation through the intervillous space of the placenta. (05 Mar 2000) |
| compensatory circulation | Circulation established in dilated collateral vessels when the main vessel of the part is obstructed. (05 Mar 2000) |
| coronary circulation | The circulation of blood through the coronary vessels of the heart. (12 Dec 1998) |
| portal | 1. A door or gate; hence, a way of entrance or exit, especially one that is grand and imposing. "Thick with sparkling orient gems The portal shone." (Milton) "From out the fiery portal of the east." (Shak) 2. The lesser gate, where there are two of different dimensions. Formerly, a small square corner in a room separated from the rest of the apartment by wainscoting, forming a short passage to another apartment. By analogy with the French portail, used by recent writers for the whole architectural composition which surrounds and includes the doorways and porches of a church. 3. <engineering> The space, at one end, between opposite trusses when these are terminated by inclined braces. 4. A prayer book or breviary; a portass. <engineering> Portal bracing, a combination of struts and ties which lie in the plane of the inclined braces at a portal, serving to transfer wind pressure from the upper parts of the trusses to an abutment or pier of the bridge. Origin: OF. Portal, F. Portail, LL. Portale, fr. L. Porta a gate. See Port a gate. <anatomy> Of or pertaining to a porta, especially the porta of the liver; as, the portal vein, which enters the liver at the porta, and divides into capillaries after the manner of an artery. Portal is applied to other veins which break up into capillaries; as, the renal portal veins in the frog. Source: Websters Dictionary (01 Mar 1998) |
| portal canals | Connective tissue spaces in the substance of the liver that are occupied by preterminal ramifications of the bile ducts, portal vein, and hepatic artery, as well as nerves and lymphatics. (05 Mar 2000) |
| portal cirrhosis | Synonym: Laennec's cirrhosis. (05 Mar 2000) |
| portal fissure | A transverse fissure on the visceral surface of the liver between the caudate and quadrate lobes, lodging the portal vein, hepatic artery, hepatic nerve plexus, hepatic ducts, and lymphatic vessels. Synonym: caudal transverse fissure, portal fissure. (05 Mar 2000) |
| portal hypertension | Any increase in the portal vein (in the liver) pressure due to anatomic or functional obstruction (for example alcoholic cirrhosis) to blood flow in the portal venous system. Indicators of portal hypertension are: oesophageal varices, haemorrhoids, enlarged veins on the anterior abdominal wall (caput Medusae) and ascites (fluid within the abdominal cavity). (27 Sep 1997) |
| portal hypertension: classification | <radiology> Presinusoidal, extrahepatic: portal vein obstruction (extrinsic compression, phlebitis, OC, coagulopathy, tumour invasion, pancreatitis, neonatal omphalitis), dynamic: traumatic/neoplastic arterioportal fistula, segmental portal hypertension: splenic/superior mesenteric vein occlusion, intrahepatic (obstruction of portal venules): congenital hepatic fibrosis, primary biliary cirrhosis, sarcoid, myelofibrosis, schistosomiasis, idiopathic noncirrhotic fibrosis, Wilson disease, reticuloendotheliosis, Felty syndrome, chronic malaria, toxic fibrosis (arsenic, copper, PVC vapors) sinusoidal, cirrhosis, sclerosing cholangitis postsinusoidal, Budd-Chiari syndrome, constrictive pericarditis, congestive heart failure (12 Dec 1998) |
